To allie/'110111, it may concern:

Beit known that I, JAMES E. AUSTIN, a citizen of the United States, and a resident of the city of Binghamton,in the county of Broome and State of New York, have invented a new and Improved Sad-Iron, of which the foilowing is a full, clear, and exact description.

-The invention relates to sad-irons heated by burning gas, and its object is to provide a new and improved sad-iron which is exceedingly simple and durable in construction and arranged to insure a uniform' heating with a minimum consum tion of gas and to produce a complete com ustion of the gas, to render the use of the sad-iron very economical and ractically odorless.

A practica embodiment of the invention is represented in the accompanying drawings forming a part .of this specification, in which similar characters of reference indicate corresponding parts in all the figures. Figure 1 is a longitudinal sectional side ele- -vation of the improvement, on the .linel-l of Fig. 2; 2 is a transverse section ofthe same, on the hne 2-2 of Fig. 1; Fig. 3 1s a.

' sectional plan view of the same, on the line end of the top A3, the two castings being securely fastened together by screws B. The

. draft flue is closed in front and provided with lateral outlets a5 one at each side. On the rear end of the body A -is formed a boss A into which screws the end of the mixing chamber C- of a Bunsen burner C, having the usual gas pipe C2, connected by a hose I) with a gas supply in the usual manner, the said gas py: C2 being provided with'a regulating cock 3 for regulating-the amount of gas admitted to the mixing chamber C. The latter is rovided with suitable air-intake openings 4 controlled by a valve C5 under the control of the operator, to admit more or less air to the mixing chamber. The valve C5 is in the form of a sleeve mounted to turn on the `mixing chamber C over the openings of said chamber. Byuse of the cock C3 and the valve C5, the proper amounts of gas and air are admitted to the mixing chamber to insure a highly combustible mixture of gas and air.

The boss A extending at the middle of the rear end A,4 is inclined inwardly and downwardly to direct theflame of the Bunsen burner in a like direction, and is provided with an enlarged spreading aperture a to encounters the sides and-undersides of the flame and by mixing with theburning gases insures complete combustion.

In order to deflect the intensely hot and expanding gases produced by the flame. of the Bunsen burner downward and over the entire upper surface of the bottom of the iron, so that the heat may be absorbed by said bottom as much as possible before thesaid gases are 'allowed to rise to-the upper portion of the hollow body A, a defiector A8 is arranged within the hollow body A, and this deflector is preferably in the form of a plate spaced from'the rear end and sides of the said hollow body, extending in aforwardly directin and terminatinf'r `a distance from the front endv of the body A. The defiector is. suspended fromv the top A3 by-a lug A0 and yscrew A10, and extends directly above the flame to prevent undue risc of the expanding and burning gases, bu't to defiect 'them downward andbring them in contact `with the entire upper surface of the bottomof the iron. Said deflector is spaced from the sides A2 and the rear of the hollowbody; to allow the' products of combustion to rise freely into 'the upper portion of the hollow body, after being thus evenly distributed over the entireupper surface of the bottom of the iron, and to pass forward above the 'partition to the draft-Hue A5. A lug A is located on the inside of the bottom A of the iron, extending transversely thereof at a distance fromthe heel of the iron,l to assist in spreading the flame.

The bottomA is provided with cor-' rugations A12.

I at which to light the i'ron.

handle E is ept cool y being lattacltied to.

the cock C3 of the Bunsen burner, so that a the hollow'body and thence out ofthe draftbody A, the sad-iron is rendered odorless,

A handle E is attached -to a protectingplate E, having lugs E2, resting on the top A3 to space the plate Efroni the said top, to keep the protecting plate EV and the handle as cool as possible. A bolt F or 'other suitable means is employed for securing the plate In using the sad-iron, the operator opens current of gas flows through the mixing chamber C and in doing so draws in air at the air-intakes C4, tov form with the gas a highly inflammable mixture which, in -passing into the hollow body A and up the draftflue, can be readily ignited at the terminal of the draft-flue A5. The gas mixture 4burning in the hollow body causes a uniform heating of the bottom A', especially as but a single flame is had, which is spread and-travels for'- ward within the hollow body from the rearspreading the flame and hot gases over the entire bottom A, the products of combustion passin between said deflector and the sides ofthe iron upward intothe upper portion of As the gas is completelyburned within the and bythe operator regulating the-cock C3 and the valve C5, a more or less intense flame may be produced within the body A. It will be 'observed that the 4gas entering the enlarged bore of the boss Ae is ignited and commences to burn therein and a partial vacuum is th-us created in said enlargement, which draws in the air with great force through the air-intakes C1 rather than from the atmosi -phere surrounding the outletof said enlargement. An intensel hot, blueflame of blow-pipe effect 'is t `us`created, which enters the interior of tlie' hollow body A at the extreme rear thereof, and is spread over the rear of the bottom of the iron by the lug A and carried over the entire corrugated surface A12 thereof, lheating'the same uniformly. Thedeflector suspended in the center of the iron is so spaced from the interionwalls vas to give nearly `the Iwhole interior of the body of the iron for the complete combustion of and forces the hot gases to pass all thus adding t-o theuiiiformity of the temperature, theproducts' of combustion passing off through the openings a5 in the sides of the draftflue \A5,` which openings also aord a convenient place As before stated, the front of the draft-flue A5 is closed, the sides only being open i Thisl prevents a backward draft of air when the' iron is in motion. The hand which holds the handle isy protected from vthe 'heat by the metal shield E that is separated from the tpp;

ofthe iron b an air s ace, `and the wo den an uniinpeded flow.

' gases the shield, and is so arranged as to move the iron with a minimum expenditure of energy.

Any desired temperature can be maintained by regulating the supply of gas and air, and the iron can be constructedin accordance with the principles set forth above, so as to accomplish all these objects and to weigh not more than six pounds. There are three principles to which it may be well' to again call attention:

The first is the admission of a mixture of gas and air through the mixing chamber C into the enlarged aperture iin the boss A in 'lhe combustible mixture of gas and air is ignited and the process of combustion commences to take place in such enlargement instead of at the outlet thereof. The gases burning in such enlargement create a partial vacuum which draws-in air through the mixing chamber C with great velocity by way of the airintakes C4, as the' vacuum cannot be filledfroni any other' direction except from the reverse of the current of gas and air, which is prevented bythe great driving force of the flame, the same being similar to a blow torch in manner and 'effect. but strong, bluish-green Bunsen flame, consible to combine with theA combustible ele- In this manner I obtain a very short .taining as large a proportion of air as it is pos-. I

ments of the gas supplied,-iii fact, as much air as can be used by a Bunsen tube supplied with air under artificial pressure.

The second principle is connected withthe deflectcr, whichdoes not extend from side tg 'side of the iron, but is spaced from the side Walls land from the'ends of the irons, thus while deecting 'the heat toward the bottom of the iron still leaves substantially the whole interior of the :iron a combustion chamber.. With my construction, the flame and hot burning Vgasesware deflected downward and distributed evenly over the ent-ire upper surface of thebottom of the iron, and at the same time the deflector allows the hot and burning to-rise into the upper portion of the hollow body lafter`- having been brought in contact with thesurface of the bottom of the iron, and the combustion of any'still unburnt gases is here completed, the products of such combustion, without any odor or smell, passing out by the draft-flue A5. In this connection it 'will be observed that the enlarged opening a is inclined downwardly from the gas supply and causes the flame toimpinge upon the rear of the bottom of the iron; also flanie,-but does not extend entirely 'across the' jiron; this lug thereforeassists in spreading XKof :the bottom of the iron in the absence of the g5 l ,'lhe third 'pripciple is theA admission of air a *hat the lug A1 is directly in the path of this-- ing the gas.

y principles makes it possible to use a hollow a comparatively small orifice, admitting a vwardly and outwardly from the lower porthrough the rear or heel of the iron through draft under the llame which aids in consum- The application and combination of these bod-y without draft-inlets of any description, except at the rear of the iron, the driving force of the flame being sufficient to draw in at such rear draft-inlet enough air external-to the llame to complete the combustion process commenced in the .enlarged aperture in the boss above referred to the driving force of the flame being sufficient to prevent any backward action when the iron is in. motion. The only outlet being at the'top of the draft-llue, before reaching which point the combustion process has been completed, all possible chalice of escaping ilamesA coming into contact with the material to be ironed -is eliminated.' The above principles working together provide a uniform heat all over the bottom of the iron. i Having thus described .my invention, I claim as new and desire to secure by Letters Patent 1. A sad-iron comprising a hollow bo'dy provided with an exterior boss extending uption thereof,l and a gas mixer connected with said boss, said boss being provided with an enlarged opening or bore at its inner end forming a chamber outside of the body in which the gases are ignited and the combustion process is corn1nenced,`tl1e burning ofl the gases in such enlargement before escaping therefrom creating a partialvacuum at such point, which in turn assists in drawing air through thelmixer, said mixer being provided with openings to the outer air.
